Thesis (MNutr (Human Nutrition))--University of Stellenbosch, 2005.
A diet high in fat results in dietary-related diseases, which have reached epidemic proportions in South Africa. Nutritional labelling has the potential to alter consumers’ knowledge of attitude and behaviour towards their fat intake. The purpose of the study was to investigate the effects of nutritional labelling on the population’s fat-intake through a systematic literature review. Electronic databases, reference lists of relevant studies and the Internet were searched, to identify studies that could help to answer the problem statement. Relevant citations were independently identified by two investigators based on the established inclusion-criteria. After this the full text of the selected citations were obtained and filtered independently by each investigator based on the inclusion- and exclusion criteria. The characteristics of each study was recorded in specially developed data extraction forms by the investigator herself and was checked by a second investigator. The primary objective of the study was to investigate nutritional labelling on food packaging. Two other forms of labelling were included to gain a more concise perception of consumers’ knowledge and practices regarding information on fat. These other forms were point-of-sale labelling (in supermarkets, in restaurants, by vending machines) and experimental labelling (labels spesifically designed to indicate the fat-content of a food item). A total of 59 relevant studies were included based on the inclusion-criteria. Although only a few studies assessed the effect of labelling on diet, there was evidence that the use of labels resulted in lower fat intake. Women older than 35 years with higher education levels, who used nutritional supplements, and who were in the maintenance stage of change to a lower fat diet, and who believed in the importance of nutrition, were between 50% to 80% higher users of information about fat than their counterparts. Fat is the food component which was most looked at on the food label (50% to 80%). Small changes in fat intake occured due to point-of-sale labelling, but labelling programmes which combined labelling with additional information on fat (e.g. pamphlets), increased visibility and nutrition education programmes, were more successful. People generally perceived products lower in fat as less pleasant, but sensory judgement of the products labelled with a low fat content were related to a person’s beliefs and concerns towards fat. Nutritional labelling can be an effective measure, which can be used to reduce the population’s fat intake; however, more research is needed to assess the effect of labelling on fat content of their diet. Regulations and education is needed to enhance the consumer’s trust in and capability in the use of labelling to make better food choices and to alter their diet. The success of labelling is dependant on a well-educated and motivated population, as well as the necessary information in a format which is understandable to the consumer.

ENGLISH ABSTRACT: Consumers are becoming more health conscious. Furthermore, time is a scarce human resource and therefore convenience is an important consideration when food choices are being made. A South African food company identified this trend and decided to develop a product that capitalised on these demands of health and convenience. The decision was made to develop a low-fat, low-cholesterol, low-saturated fatty acid, low-trans fatty acid, high-fibre wheat product with an intermediate glycemic index (GI). The market in Stellenbosch was scouted to determine whether a similar product already existed. Six products that made nutrient-, health- or any other claims were identified. Not one of the identified products, however, conformed to meet the requirements of the Department of Health for the product characteristics that were set. Therefore, the decision was made to continue the development of the low-fat, low-cholesterol, low-saturated fatty acid, low-trans fatty acid, high-fibre wheat product with an intermediate glycemic index (GI). To qualify as a low-fat product, the product had to contain less than 3 % fat. The ingredients were chosen with their fat content in mind. Fruit pulp is widely used in the preparation of baked low-fat products and was also used in this study to eliminate the use of butter, margarine and oil, but also to achieve the additional product criteria that was set by the food company, namely a chewy texture and a fruity flavour. Ingredients like soya flour, oatmeal, oats and wheat bran were chosen to increase the fibre content of the product, because all of these products have a fibre content of 10 g or more per 100 g. Two products were developed during 23 experiments. Except for the high fibre claim, both products met the criteria that were set before the development started, namely a low-fat, low-cholesterol, low-saturated fatty acid, low-trans fatty acid, high-fibre content and a calculated intermediate glycemic index (GI). One of the two concept products that were developed were chosen by an experienced panel to serve as basic product for an empirical study on the effect of different fibre levels on the glycemic index. Five different fibre levels were formulated by manipulating the amounts of wheat bran and oatmeal. The basic formula contained 6,25 % fibre and the other fibre levels were identified as: 4,39; 5,31; 7,45 en 8,17 %. The fibre levels were equal-distant. The prediction was made that the GI-value of the product will decrease as the fibre levels increase and the theoretical calculations confirmed this prediction. The real GI-values that were determined by blood glucose testings, however, showed an increase in GI-value up to the 6,25 % fibre level, followed by a.decrease in GI-value to the 8,17 % fibre level. It became apparent that more than just fibre played a role in the GI-values of the products. It is proposed that the results explained by fibre behaviour, starch gelatinisation and starch hydrolysis. Hundred households in Stell enbosch tested the developed product. Two fieldworkers identified 25 consumers in four retail stores in Stellenbosch and gave them the product and the questionnaire, which they had to complete at home after tasting the product. The questionnaires were then collected from the respondents' houses. A recognised measurement instrument, which is used by the South African food industry to determine the acceptability of a newly developed product, was used for assesing the results. The results showed that the orange flavour of the product led to a low overall acceptability of the developed product and that the other product concept (that was developed during the recipe development phase and not chosen by the panel) should be considered for testing its market potential. Another facet of the questionnaire determined the effect of buying practices, health consciousness and consumer knowledge on the consumer acceptability of the low-fat, high-fibre wheat product with an intermediate-GI-value. No correlation between these factors and consumer acceptability of the low-fat, high-fibre wheat product with an intermediate-GI-value were found.
AFRIKAANSE OPSOMMING: Die verbruiker word al meer gesondheidsbewus: Terselfdertyd is tyd 'n skaars menslike hulpbron, en word gerief gevolglik 'n belangrike oorweging tydens voedselkeuses. 'n Suid-Afrikaanse voedselmaatskappy het hierdie neigings geidentifiseer en besluit om 'n produk te ontwikkel wat aan hierdie vereistes van gesondheid en gerief voldoen. Daar is besluit om 'n lae vet-, lae cholesterol-, lae versadigdevetsuur-, lae transvetsuur-, hoe veselgraanproduk met 'n intermediere glukemiese indeks (GI) te ontwikkel. Die Stellenbosse mark is verken om vas te stel of daar reeds soortgelyke produkte op die mark was. Ses produkte wat nutrientinhoud-, gesondheid- of ander aansprake maak, is geidentifiseer. Geeneen van die produkte het egter aan die Departement van Gesondheid se konsepregulasies betreffende die etikettering van voedingsmiddels vir bogenoemde produkeienskappe voldoen nie. Gevolglik is besluit om met die ontwikkeling van die lae vet-, lae cholesterol-, lae versadigdevetsuur-, lae transvetsuur-, hoe veselgraanproduk met 'n intermediere GI voort te gaan. Om as 'n laevetproduk te kon kwalifiseer, moes die produk minder as 3 % vet bevat. Die bestanddele moes dus met inagneming van hul vetinhoud gekies word. Vrugtepulp word algemeen gebruik in die bereiding van gebakte laevetprodukte en is ook in hierdie studie gebruik om die gebruik van botter, margarien of olie te vermy, maar ook om aan die addisionele produkkriteria wat deur die maatskappy gespesifiseer is, naamlik 'n sagte tekstuur en vrugtige geur, te voldoen. Bestanddele soos soja-, hawermeel, hawer- en koringsemels is gekies om die veselinhoud van die produk te verhoog, aangesien hierdie bestanddele meer as 10 g vesel per 100 g bevat. Twee produkte is deur middel van 23 eksperimente ontwikkel. Met die uitsondering van die hoeveselinhoudaanspraak, het beide produkte aan die vereistes wat gestel is, naamlik 'n laevet-, laecholesterol-, laeversadigdevetsuur-, laetransvetsuur- en 'n hoeveselinhoud en 'n beraamde intermediere GI, voldoen. Een van die konsepprodukte is deur 'n ervare paneel gekies vir die empiriese studie waar die effek van verskillende veselvlakke op die GI bepaal is. 'n Standaard formule is aangepas om vyf verskillende veselvlakke te verkry deur die koringsemel- en hawermeelhoeveelhede te manipuleer. Die basisformule het 6,25 % vesel bevat en twee veselvlakke is daarbo en -onder as ge·identifiseer: 4,39; 5,31; 7,45 en 8,17 %, dit wil sê, veselvlakke met dieselfde grootte verskille. Daar is voorspel dat die GI-waarde van die produkte sou daal met 'n toename in die veselinhoud van die produk en die teoretiese berekeninge van die GI-waarde het hierdie voorspelling gestaaf. Die werklike GI-waardes wat met behulp van bloedglukoseresponse bepaal is, het egter 'n toename in GI-waarde tot by die 6,25 % veselvlak, gevolg deur 'n afname tot by die 8,17 % veselvlak aangedui. Dit het duidelik geword dat meer as slegs die veselinhoud 'n rol gespeel het by die GI-waarde van die produk. Die resultate is gevolglik aan die hand van die veselgedrag, styselgelatinisasie en styselhidrolise verklaar. Die verbruikersaanvaarbaarheid van die ontwikkelde laevet-, hoeveselproduk is by 100 huishoudings in Stellenbosch getoets. Twee veldwerkers het die verbruikers in vier kleinhandelaars in Stellenbosch genader en produkte met 'n gepaardgaande vraelys aan hulle oorhandig. Die produkte is tuis qeevalueer en die vraelyste is weer ingesamel. Ook vervat in die vraelys was 'n erkende meetinstrument wat deur die Suid-Afrikaanse voedselindustrie gebruik word vir die bepaling van verbruikersaanvaarbaarheid van 'n nuutontwikkelde produk. Uit die resultate het dit geblyk dat die lemoengeur van die produk gelei het tot die lae verbruikersaanvaarbaarheid van die ontwikkelde produk, en dat die ander produkkonsep (wat tydens die resepontwikkelingsfase ontwikkel is, en nie deur die ervare paneel gekies is nie) vir bemarkingspotensiaal getoets hoort te word. Die data wat uit die vraelyste ingesamel is, is ook gebruik om die effek van aankooppraktyke, gesondheidsbewustheid en verbruikerskennis op die verbruikersaanvaarbaarheid van die laevet-, hoeveselgraanproduk met 'n interrnediere-Gl-waarde te bepaal. Daar is geen verwantskap tussen hierdie faktore en die verbruikersaanvaarbaarheid van die laevet-, hoëveselgraanproduk met 'n intermedlere-Gl-waarde, gevind nie.

Abstract:

We sought to investigate the role of the Planar Cell Polarity (PCP) pathway in neuronal positioning along the Anterior-Posterior (AP) axis of C. elegans, and chose the worm’s DD-type motor neurons as a model. The six DD neurons (DD1-DD6) are evenly spaced in the ventral nerve cord of wild type animals. Here we showed that mutations in core PCP genes caused DD neuron spacing and positioning defects. prkl-1 double mutant combinations with vang-1 and fmi-1 showed a suppression of the more severe prkl-1 single mutant defects, which was evidence of genetic interactions between these PCP components. We also conducted a candidate screen of Frizzled, Dishevelled, Wnt, and ROCK genes, and found that dsh-1/Dishevelled, mom-2/Wnt and let-502/ROCK also played roles in DD neuronal positioning. Both vang-1 and prkl-1 were found to function within the nervous system to guide DD neuronal positioning, and prkl-1 was further identified as playing a cell autonomous role. The origins of observed DD neuron anterior positioning defects were investigated during embryogenesis, in which 1.5 fold stage prkl-1(ok3182) embryos displayed delayed intercalation of the DD neurons. This represents a novel role for the PCP pathway in mediating DD neuronal intercalation.

ENGLISH ABSTRACT: The Fruit Unit of Tiger Brands is annually responsible for the canning of 75 000 tons of fruit of which apricots constitutes approximately twenty percent. The canning of apricots is subject to a few unique challenges with regard to production planning. The challenges are the unpredictable fruit sizes, unpredictable fruit quality, unpredictable fruit degradation in cold storage, unknown starting date for production and the uncompromisable end of production before Christmas day. These uncertainties led to the fact that no formal production planning for apricots had been done in the previous years of operation. The primary aim of this study is to reduce the risks with regard to production, apricot size and apricot quality by effectively forecasting the expected nett result thereof. This will quantify the resultant products available to marketing personnel and give a measure to evaluate and control production performance. The problem is addressed by organising and presenting historical data such that forecasts of future outcomes would become possible. Clear trends are present on throughput and fruit degradation over time, making forecasting of these two uncertainties quite simple. The forecasting of fruit size is however more problematic, especially because of the lack of sufficient data. It was proposed that the four main fruit size categories be described by using probability distributions fitted over the actual data of the last four years. The large variation on these distributions, probably caused by the lack of sufficient data, rendered this method unsuitable. It was decided that the best estimate of the percentage of each fruit size to be expected, was the average of the derived distributions. The model constructed of the above forecasts is suitable for the estimating of the quantities of specific products that would be available as output from the production process. The model is however not suitable for the evaluation and control of production processes. It is proposed that evaluation and control of production be achieved by using control charts derived from the same historical data. The production control charts are constructed from actual, cumulative production output from the last four years. Linear regression was done on this data to establish a trend line with two sigma limits plotted on the same chart. These charts could be used effectively to monitor daily production output to establish if the commitment towards marketing would be achieved. The lack of data for analysis puts a question mark on the statistical significance of the model. The model is viewed to be a first step in the elimination of uncertainties of raw materials and production variances by making use of historical performance data. The model and control charts will become more and more statistically significant if future actual performance data is incorporated. The model could also be drastically improved if detailed agricultural models for the prediction of apricot size and quality, based on climatic and soil conditions during the growing period were available. The development of such models could be the subject of future studies.
AFRIKAANSE OPSOMMING: Die Vrugte eenheid van Tiger Brands is jaarliks verantwoordelik vir die inmaak van naastenby 75 000 ton vrugte. Appelkose maak twintig persent van hierdie volume uit. Die inmaak van appelkose is onderhewig aan unieke uitdagings ten opsigte van produksiebeplanning. Die uniekheid is gesetel in die onvoorspelbaarheid van vruggrootte, die jaarlikse verskille in vrugdegradering tydens opberging, die onvoorspelbaarheid van die begindatum van produksie en die absolute vereiste om voor Kersdag produksie te voltooi. Hierdie onvoorspelbaarhede het tot gevolg dat daar tot op hede geen formele produksiebeplanning vir appelkose gedoen is nie. Die primêre doelwit van die studie is om die risiko's ten opsigte van produksie, appelkoosgehalte en appelkoosgrootte te verminder, deur die impak daarvan vooruit te skat. Sodoende sal die produkte wat vir bemarking beskikbaar gestel behoort te word ook beter bekend en beheerbaar wees. Die probleem word aangespreek deur geskiedkundige data sodanig te verwerk en te organiseer dat vooruitskattings daarmee gedoen kan word. Baie duidelike tendense ten opsigte van deurset en vrugdegradering oor tyd is deur middel van die geskiedkundige data waarneembaar, wat vooruitskatting van die twee faktore redelik vergemaklik. Die vooruitskatting van vruggrootte bly egter problematies, veral as gevolg van die gebrekkige geskiedkundige data wat beskikbaar is. Daar is gepoog om die vier gespesifiseerde vruggrootte kategorieë deur middel van waarskynlikheidsverdelings te beskryf, maar die gebrekkige data en groot variasie van die data en verdelings maak die tegniek ongeskik. Gevolglik is daar besluit om slegs die gemiddeld van hierdie verdelings as 'n beste raming te gebruik van die verwagte hoeveelheid van elke vruggrootte. Die model wat uit bogenoemde manipulering van data afgelei word, word gereken geskik te wees vir die raming van hoeveelhede van spesifieke produkte wat vir verkope beskikbaar sal wees. Die model is egter onvoldoende vir produksiebeheer en evaluasie. Produksie evaluasie sal egter met behulp van produksiebeheer kaarte wat ook van geskiedkundige prestasie afgelei is, gedoen word. Die produksiebeheer kaarte is kumulatiewe werklike fabrieksprestasie waardeur 'n regressielyn gepas is, met twee sigma afwykingslyne weerskante van die regressielyn geplot. Hierdie kaarte sal gebruik word om daaglikse produksie prestasie te plot en te interpreteer of die kommitment teenoor bemarkingspersoneel steeds haalbaar sou wees. Die model en die produksiebeheer kaarte is afgelei van slegs vier vorige seisoene se produksiedata. Die tekort aan relevante data plaas die betekenisvolheid van die afleidings dus onder verdenking. Die model en kaarte word beskou as 'n eerste poging om die risiko van grondstof- en produksievariasies te verminder deur die vooruitskatting van die uitsette met behulp van geskiedkundige prestasie. Die model en kaarte sal met die inkorporering van toekomstige seisoenale data meer statisties beduidend word. Die model sou ook verbeter kon word deur detail landboukundige modelle wat appelkoos gehalte en grootte verbind met klimatologiese en grondkundige kondisies tydens die verbouingsproses van die vrugte. Hierdie verbetering word egter voorgestel vir 'n verdere studie onderwerp.

Abstract:

Miljöproblemen blir allt mer aktuella, människor blir mer upplysta och utbudet av de ekologiska livsmedlen ökar i butikerna. Allt fler börjar handla ekologiskt, men fortfarande är det merparten som väljer att inte handla ekologiskt trots att de har en positiv inställning till ekologisk konsumtion. För att klargöra vad som ligger bakom konsumentens val av varor intervjuades fyra informanter, två som till vardags handlar ekologiskt och två som handlar konventionellt. Det finns många anledningar till varför inte konsumenter väljer att handla ekologiskt. När konsumenten står för ett val av vara så är det flera kriterier som spelar in så som kvalitet, hälsa, pris och etiska aspekter. Förutom dessa kriterier så handlar konsumenten utefter vana, kunskap och grupptillhörighet. Det visade sig att de båda ekologiska informanterna hade stor kunskap och engagemang i att handla ekologiskt, och såg det mervärde som ekologiska produkter har, och struntar därför i prisskillnaderna. Informanterna som handlade konventionellt hade inte kunskap om ekologiska varor och såg därmed inte mervärdet i de ekologiska varorna, utan handlade istället utefter vana och kvalitet.

These days the environmental problems are getting more in focus and the supply of organic food is increasing in the supermarkets. More people are buying organic food than before but the majority still chooses to buy conventional food despite that they’re often positive towards the organic option. To clarify what lies behind the consumers´ shopping habits I have interviewed four informants. Two who usually buy organic food and two who usually buy conventional food. There are several reasons why the consumer chooses to buy conventional food and not the organic option. When the consumer faces several options there are different factors such as quality, health, prize and ethical aspects that matter. Their existing shopping habits, knowledge and their social identity are also factors that matter. The two ecological consumers had knowledge and interest in organic food and despite the prize difference they appreciated the extra value of it. The conventional consumer lacked knowledge of organic food and didn’t appreciate its advantages. Instead they choose to buy food after their habits and the quality of the products.

ENGLISH ABSTRACT: Physical activity is an integral part of children's lives. It makes an essential contribution to their physical, psychological and social well-being. Often, it is through movement and active play that children learn to discover themselves. This movement and play sometimes serves as a medium for communication. Unfortunately, various research studies show that children are not active enough and lead ever increasing sedentary lifestyles and these lifestyles lead to various types of hypo-kinetic diseases. Technology, as well as the phasing out of structured physical education in schools, are aspects that are responsible for the decrease in activity levels of children. The primary aim of this study was to determine if present-day children's (Grades 1 - 3) physical abilities have improved or worsened over the years. Movement tests from Katzenellenbogen (1976) were used to test movement abilities of these children. Adapted questionnaires from Van Deventer (1999) were used to construct the lifestyle patterns of learners and to get information concerning movement programmes from teachers at schools. The sample population (N=372) was selected from four schools (two previously disadvantaged and two former Model C schools) in the Stellenbosch area. The tests evaluated, inter alia the following, velocity, velocity and power, power, velocity and accuracy, accuracy and precision. Children from the previously disadvantaged and former Model C schools, as well as age and sex were compared. A comparison with the 1976 study of Katzenellebogen was also done. The latter study only involved girls and was undertaken only at White schools. The coding of the variable data was done in a computer format, coded and statistically analysed. Averages are compared through the Analyses of Variance (ANOVA). From the results of the study, it can be concluded that children at the former Model C schools fared better in most of the tests and it is evident that boys generally are more active than girls. As far as the comparison with the 1976 study is concerned, present-day girls fared worse in almost all the tests. The weight of the 9 year old girls increased by as much as 7.2 kg. This study can therefore be a starting point for further study attempting to combat the tendency of inactivity amongst the youth of today.
AFRIKAANSE OPSOMMING: Fisieke aktiwiteit is 'n integrale deel van kinders se lewens. Dit maak 'n essensiële bydrae tot hul fisieke, psigologiese en sosiale welstand. Dit is dikwels deur beweging en aktiewe spel wat kinders leer om hulself te ontdek. Hierdie beweging en spel dien ook soms as 'n medium vir kommunikasie. Ongelukkig toon verskeie navorsing dat kinders nie aktief genoeg is nie en al hoe meer sedentêre leefstyle handhaaf, wat lei tot allerhande hipokinetiese siektetoestande. Tegnologie, asook die uitfassering van gestruktureerde Liggaamlike Opvoeding in skole is aspekte wat verantwoordelik gehou word vir die afname in aktiwiteitsvlakke van kinders. Die primêre doel van hierdie studie was om te bepaal of hedendaagse kinders (Graad 1 tot 3) se bewegingsvermoëns oor die jare heen verbeter of verswak het. Bewegingstoetse uit Katzenellenbogen (1976) is gebruik om bewegingsvermoëns van die kinders te toets. Aangepaste vraelyste uit Van Deventer (1999) is gebruik om die leefstylpatrone van leerders vas te stel en om inligting aangaande bewegingsprogramme in die skole by onderwysers te bekom. Die proefpersone (N=372) is uit vier skole (twee voorheenbenadeelde [VB]- en twee voormalige Model-C [VMC]-skole) in die Stellenbosch omgewing geselekteer. Die toetse het die volgende veranderlikes gemeet: snelheid; snelheid en dryfkrag; dryfkrag; snelheid en akkuraatheid; akkuraatheid en presiesheid; getoets. Kinders van VB- en VMC-skole, ouderdomme en geslagte is met mekaar vergelyk. Daar is ook 'n vergelyking met die 1976-studie van Katzenellenbogen getref. Die 1976-studie van Katzenellenbogen het slegs dogters ingesluit en is slegs by Blanke skole onderneem. Die veranderlikes se datametings is in rekenaarformaat gekodeer en statisties verwerk. Gemiddeldes is vergelyk deur middel van analise van variansie (ANOVA). Uit die resultate van die studie kan tot die gevolgtrekking gekom word dat kinders by die VMC-skole beter in meeste van die toetse gevaar het en dit blyk ook dat seuns oor die algemeen meer aktief is as dogters. Wat die vergelyking met die 1976-studie betref, het hedendaagse dogters swakker gevaar in byna al die toetse. Die 9-jarige dogters het ook met soveel as 7.2 kg in gewig vermeerder. Hierdie studie kan dus as 'n beginpunt dien vir verdere studie in 'n poging om die tendens van onaktiwiteit onder vandag se jongmense te bekamp.

Abstract:

Aim Nutrient profiling is defined as “the science of classifying or ranking food items according to their nutritional composition for reasons related to preventing disease and promoting health, and can be used to govern the criteria under which nutrient and/or health claims may be made”. The validation of a nutrient profiling model (NPM) is an essential part of the model development process, and is extremely important for the model to meet basic scientific criteria. This mini-dissertation investigated the content and convergent validity of a suitable NPM for South Africa. Method Content validity was tested for by comparing the NPM classification of 131 “indicator” foods with the classification of the “indicator” foods by the Food Based Dietary Guidelines (FBDGs). Convergent validity was tested for by comparing the standard ranking of a representative data set of food items (n = 128) by nutrition experts with the classification of the food items by the NPM. The questionnaire asked respondents to rank 40 foods (electronically generated from a master list of 128 foods) according to the nutritional information provided from “more healthy” to “less healthy” using a six point Likert scale. The 128 foods were selected to be representative of the South African diet. These questionnaires were sent via e-mail to all full members (n = 1105) of the Association of Dietetics in South Africa. The draft “Guiding principles and framework manual for the development or adaptation of nutrient profile models” dated 22 February 2011 (WHO, 2011), was used as a guide in the validation process of the NPM. Results The NPM showed good content validity: the way that the NPM categorises foods correspond well with that of the FBDGs (kappa statistic = 0.73). Two hundred and ninety two responses were received (26.4%) from the nutrition experts, these responses were used to rank the 128 foods by the average score which they received from the nutrition experts. The NPM also showed good convergent validity: the NPM classification of foods had a good correlation with the standard ranking of foods by dietitians (r = 0.853; p = 0.0001). Conclusion The NPM demonstrated good content validity by classifying food items in way that supports the FBDGs with the exception of a few processed food items and combined food items. The NPM also demonstrated good convergent validity by classifying food items in accordance with the views of nutrition experts in South Africa.

Abstract:

Energi til romoppvarming og til produksjon av varmt forbruksvann utgjør en stor del av den totale energibruken i bygninger, og fossil energi eller elektrisitet blir ofte benyttet. Bruk av fossil energi og elektrisitet produsert av fossile kilder bidrar til global oppvarming, og det er derfor ønskelig å redusere bruken av både fossil energi og elektrisk energi. Det er da aktuelt å bruke fornybar varme, og et solvarmeanlegg som dekker deler av varmebehovet i bygninger kan være et godt alternativ. Det ble derfor gjort et litteraturstudie over mulighetene for å utnytte soloppvarming av vann i Norge, med fokus på steder med et klima tilsvarende Oslo-klima. Det ble også gjort en analyse av mulighetene for å utnytte et solvarmeanlegg i et spesifikt kontorbygg i Oslo som skal bygges ut. Kontorbygget bruker nå fjernvarme til vann- og romoppvarming, men andre alternativer undersøkes. For å undersøke mulighetene for å utnytte et solvarmeanlegg i kontorbygget ble det gjort simuleringer i to simuleringsprogram, utført en økonomisk analyse, og en kort analyse av potensiell reduksjon av klimagassutslipp. Til slutt ble det gjort en kort analyse av et nytt solvarmeanlegg for oppvarming av varmtvann i et grendesenter i Oslo, med blant annet en barnehage, skole, og en flerbrukshall. Analysen av grendesenteret er basert på temperaturmålinger fra solvarmeanlegget. Litteraturstudiet indikerer at solvarmeanlegg passer generelt best for bygninger med et stort varmtvannsbehov, og bygninger med et stort varmtvannsbehov i forhold til totalt varmebehov. Dette medfører at idrettshaller og lavenergiboliger og passivhus er best egnet for solvarmeanlegg. For kontorbygg vil et solvarmeanlegg ikke kunne dekke noen særlig stor andel av totalt varmebehov. Det vil imidlertid kunne bidra til at krav i nye standarder og forskrifter blir oppfylt. I tillegg vil et solvarmeanlegg kunne bidra til en bra energimerking av kontorbygg og bygg generelt. Hvis det skal bygges et solvarmeanlegg i tilknytting til kontorbygget i Oslo anbefales det å bygge et solvarmeanlegg for vann- og romoppvarming med solfangere på taket. Solvarmeanlegget som anbefales har et solfangerareal på 100 m2 og en lagringskapasitet på 5000 liter. Solvarmeanlegget bruker en god vakuumrørsolfanger som er vendt mot sør og har en helningsvinkel på 60 °. Solvarmeanlegget gir en årlig varmeproduksjon på 13,9 % av årlig energibehov til vann- og romoppvarming. Resultatene fra den økonomiske analysen av solvarmeanlegget til kontorbygget er usikker. Resultatene er avhengig av hva levetiden til solvarmeanlegget blir og hvor stor kostnaden knyttet til planlegging og oppføring av solvarmeanlegget er. Hvis levetiden til solvarmeanlegget er 20 år og kostnad knyttet til planlegging og oppføring av solvarmeanlegget er 39 % av total investeringskostnad vil anbefalt solvarmeanlegg gi et tap på omtrent 209 328 kr, det trengs da en støtte på 2,2 kr/kWh produsert fornybar varme for at solvarmeanlegget skal gå i null. Hvis levetiden til solvarmeanlegget er 20 år og kostnad knyttet til planlegging og oppføring er 20 % av total investeringskostnad vil solvarmeanlegget gi en gevinst på omtrent 53 766 kr. Hvis levetiden til solvarmeanlegget er 30 år og kostnad knyttet til planlegging og oppføring er 39 % av total investeringskostnad vil anbefalt solvarmeanlegg gi et tap på omtrent 65 421 kr, det trengs da en støtte på 0,7 kr/kWh produsert fornybar varme for at solvarmeanlegget skal gå i null. Hvis levetiden til solvarmeanlegget er 30 år og kostnad knyttet til planlegging og oppføring er 20 % av total investeringskostnad vil solvarmeanlegget gi en gevinst på omtrent 197 673 kr. Anbefalt solvarmeanlegg vil redusere årlig klimagassutslipp fra kontorbygget med omtrent 8924 kg CO2-ekvivalenter. Dette tilsvarer omtrent å fjerne 1,5 biler fra veiene i året. Resultatene viser at det er mulig å bruke solvarmeanlegg som kan ta en del av varmebehovet i kontorbygninger i et klima tilsvarende Oslo-klima. Om solvarmeanleggene er lønnsomme kommer an på hvor lang levetid solvarmeanleggene får og hvor stor investeringskostnaden blir. Mange av de simulerte systemløsningene for solvarmeanlegg i kontorbygget ble aldri lønnsomme, selv med lang levetid og optimistisk investeringskostnad. Det er derfor viktig å gjøre en grundig analyse før en bygger store solvarmeanlegg for kontorbygninger. Beregninger indikerer at solvarmeanlegget på Storøya Grendesenter har produsert varme tilsvarende 5,8 % av totalt energibehov til oppvarming av varmtvann i perioden anlegget har blitt analysert. Beregningene er basert på temperaturmålinger fra og med uke 11 til og med uke 14, og fra og med uke 18 til og med 28. mai i uke 21. Beregningene er svært usikre siden de bare er basert på temperaturmålinger, men de indikerer at solvarmeanlegget ikke fungerer optimalt.

Thesis (MComm)--Stellenbosch University, 2004.
ENGLISH ABSTRACT: Like any other item of expenditure, interest expenditure's deductibility is determined by subjecting it to the tests laid down in the general deduction formula contained in section 11(a), together with section 23(f) and 23(g) of the Income Tax Act, as well as the special deductions applicable to interest. In this study there will be only concentrated on the tests laid down in the general deduction formula contained in section 11(a), together with section 23(f) and 23(g) of the Income Tax Act. The general test according to section 11(a) as laid down by the courts to ascertain if an expense incurred in trade is deductible, is firstly to ascertain the act entailing the expenditure. If it is performed for the purpose of earning income, the expenditure attendant upon is deductible. Secondly, the closeness of the connection between the expenditure incurred and the trade must be ascertained. If the expense incurred is so closely connected with the business operation that it may be regarded as part of the cost of performing it, the expenditure will be deductible. The courts have considered many factors to ascertain if interest expenditure complies with the statutory requirements as set out in section 11(a), read together with section 23(f) and 23(g) of the Income Tax Act. There seems to be one test which can be applied to most of the statutory requirements and can be seen as the conclusive factor in determining the deductibility of interest expenses and that is the test of the original purpose of the loan that leads to the interest expense. Firstly in this study, the factors considered by the courts to ascertain if the deductibility of an interest expenditure complies with the statutory requirements as set out in the introduction of section 11(a), together with section 23(f) and 23(g), will be examined with specific reference to the purpose of the loan. Then the possibility of a change in the original purpose of a loan and the effect on the deductibility of an interest expenditure will be examined.
AFRIKAANSE OPSOMMING: Soos enige ander uitgawe, word rente uitgawes se aftrekbaarheid bepaal deur dit te onderwerp aan die toetse soos neergele in die algemene aftrekkingsformule, vervat in artikel 11(a), saamgelees met artikel 23(f) en 23(g) van die Inkomstebelastingwet, asook die spesiale aftrekkings wat op rente van toepassing is. In hierdie studie word slegs op die algemene aftrekkingsformule, vervat in artikel 11(a), saamgelees met artikel 23(f) en 23(g) van die Inkomstebelastingwet gekonsentreer. Die algemene toets volgens artikel 11(a) wat deur die howe neergele is om te bepaal of 'n uitgawe aangegaan in 'n bedryf aftrekbaar is, is om eerstens te bepaal of die handeling waaraan die uitgawe verbind is by die voortbrenging van inkomste aangegaan is en tweedens of die uitgawe wat aangegaan is nou genoeg verwant is aan die bedryf sod at dit as deel van die koste beskou kan word om die bedryf te beoefen. Die howe het verskeie faktore oorweeg om te bepaal of die aftrekbaarheid van rente uitgawes voldoen aan die statutere vereistes soos bepaal deur artikel 11(a), saamgelees met artikel 23(f) en 23(g) van die Inkomstebelastingwet. Daar blyk een toets te wees wat op die meeste statutêre vereistes toegepas kan word en wat ook as die bepalende factor beskou kan word om die aftrekbaarheid van rente uitgawes te beoordeel en dit is die oorspronklike doel waarmee die lening aangegaan is wat die rente uitgawe tot gevolg het. In hierdie studie word eerstens ondersoek ingestel na die faktore wat die howe oorweeg om te bepaal of 'n rente uitgawe aan die vereistes, soos uiteengesit in die inleiding van artikel 11(a), saamgelees met artikel 23(f) en 23(g), voldoen met spesifieke verwysing na die doel waarmee 'n lening aangegaan word. Die moontlikheid word dan ondersoek dat die oorspronklike doel van die lening kan verander en watter effek dit op die aftreknbaarheid van ‘n rente uitgawe kan hê.

ENGLISH ABSTRACT: There is a growing interest in the investigation of the value of music to the development of cognitive, social, personal and motor skills pertaining to infants. Research has shown that the inclusion of music in intervention programs for physically and cognitively disabled children could have a positive influence on the development of several of their skills. Against this background the reactions and development of four children with Down syndrome from a school for the disabled in Bellville were investigated from a holistic point of view during their participation in a music stimulation program. The music stimulation program presented in this study was compiled after consulting existing well-proven music appreciation programs for non-disabled children. Some of the activities extracted from these programs were adjusted where necessary. At times nonmusical activities were also combined with music in order to address a diversity of skills by means of music. Results after the completion of the program indicated that music has the potential to enhance the development of several skills and intelligences, as identified and described by Gardner (1983), of children with Down syndrome. Although it was difficult to determine whether music was responsible for some of the improvements that were observed, the results from this study indicated that children with Down syndrome can benefit from a structured music stimulation program.
AFRIKAANSE OPSOMMING: Die waarde van musiek ten opsigte van die ontwikkeling van kognitiewe, sosiale, persoonlike en motoriese vaardighede by kleuters word toenemend ondersoek. Navorsing het getoon dat die insluiting van musiek by intervensieprogramme vir fisies en kognitief gestremde kinders die ontwikkeling van verskeie vaardighede positief kan beïnvloed. Teen hierdie agtergrond IS die reaksies en ontwikkeling van vier kinders met Downsindroom vanuit 'n holistiese oogpunt tydens deelname aan 'n musiekstimuleringsprogram ondersoek. Hierdie kinders het 'n skool vir gestremdes in Bellville bygewoon. Die musiekstimuleringsprogram wat tydens die studie gebruik is, is saamgestel deur bestaande musiekwaarderingsprograrnme vir nie-gestremde kleuters wat oor 'n aantal jare beproef is te raadpleeg en, waar nodig, die aktiwiteite aan te pas. Nie-musikale aktiwiteite is soms met musiek gekombineer ten einde 'n verskeidenheid van vaardighede deur middel van musiek aan te spreek Die resultate van die voltooiing van die program het daarop gedui dat musiek die potensiaal het om 'n positiewe invloed op die ontwikkeling van verskeie vaardighede en intelligensies, soos geïdentifiseer en beskryf deur Gardner (1983), op kinders met Downsindroom uit te oefen. Hoewel dit soms moeilik was om te bepaal of musiek verantwoordelik was vir sommige van die verbeterings wat opgemerk is, het dit uit die resultate van hierdie studie geblyk dat kinders met Downsindroom kan baat vind by 'n gestruktureerde musiekstimuleringsprogram.

Thesis (MPhil)--Stellenbosch University, 2012.
ENGLISH ABSTRACT: According to the results of the Annual National Assessment, ANA, the reading skills (reading ability, reading comprehension and fluency in reading) of children in South African schools are not up to standard (Department of Basic Education, 2011:20). Only 28% of Grade 6 learners and 35% of Grade 3 learners achieved the standardized levels for literacy and language in their respective grades. Further research (De Witt, 2009:619) also proved that only 35% of Grade R learners reached the minimum requirements for the development of literacy according to their age (5-6 years). The focus of this research is the advancement of Emergent Literacy through multimedia as preparation for elementary reading to ensure reading ability, comprehension and fluency. To promote Emergent Literacy the researcher should: - determine through research at what stage the natural developmental pattern of the learn to read process starts with toddlers - determine the process to follow for the development of literacy - determine the necessary skills required for reading fluently and with comprehension up to an age related standard - develop a multimedia program based on and guided by the process of literacy development - observe, record and analyze the effect of such a multimedia program for toddlers/learners. The research approach adopted in this thesis includes a case study with pre-school children between the ages of 2 and 5 years old. A learner aged 13, who had not yet achieved the required literacy levels for her age, was also included in the study. Data collection was done through interviews with and observations of toddlers/learners using a multimedia program that consisted of Foundation Skills for Emergent Literacy and General Reading Standards for Early Literacy. The multimedia program was designed based on an in-depth literature review of existing research. This research was focused on determining at which stage natural literacy development begins and what process should be followed to facilitate such development. The multimedia program covers the aspects of Phonological Processing, Print Awareness, Oral Language Skills, Emergent Reading, Print Knowledge and Early Word Recognition, Language Development and Listening and Reading Comprehension. The findings from this research provide evidence that highlights the value of reading, singing and repeating rhymes, songs and stories to children. The different methods of reading to children, the print–reference style to teach letters and sounds as well as inferencing that leads to comprehension, are proven by this research to be very important.
AFRIKAANSE OPSOMMING: Die standaard van leesvaardigheid (leesvermoë, -begrip en –vlotheid) in Suid-Afrikaanse skole is ondergemiddeld volgens die uitslag van die verslag oor die Jaarlikse Nasionale Assessering (in Engels: Annual National Assessment of afgekort ANA), wat aandui dat net 28% van alle Gr. 6-leerders en net 35% van alle Gr. 3-leerders die standaardvlakke vir geletterdheid en taal vir die betrokke grade behaal het (Departement van Basiese Onderwys, 2011:20). Verdere navorsing het egter ook bewys dat slegs 35% van Gr. R-leerders die minimum vereistes van geletterdheidsontwikkeling vir hulle ouderdom (5-6 jaar) bereik. Dit impliseer dat die meerderheid leerders Gr. 1 begin sonder die nodige vooraf vaardighede om te kan leer lees (De Witt, 2009:619). Die fokus van hierdie studie is om Vroegtydige Geletterdheid te bevorder deur middel van multimedia as voorbereiding vir aanvangslees om leesvermoë, -begrip en -vlotheid te verseker. Om Vroegtydige Geletterdheid te kan bevorder, moet vasgestel word volgens navorsing: - op watter stadium die natuurlike ontwikkelingspatroon van leer-lees by die kleuter begin - die proses om te volg vir geletterdheidsontwikkeling - watter vaardighede aangeleer behoort te word om op standaard, vlot en met begrip te kan lees volgens ouderdom - om ‘n multimediaprogram volgens die geletterdheidsontwikkelingsproses op te stel - wat die uitwerking van ’n multimediaprogram op kleuters/leerders is. In hierdie navorsing word ‘n gevallestudie as die navorsingsstrategie gebruik met kleuters/leerders vanaf 2 jaar tot 5 jaar oud en een 13-jarige leerder wat ingesluit word omdat sy nog nie die ontwikkelingsvlak vir lees volgens haar ouderdom bereik het nie. Die data vir die Grondslagvaardighede vir Vroegtydige Geletterdheid en Algemene Leesstandaarde vir Geletterdheid word ingesamel deur onderhoudvoering en waarneming. ‘n Multimediaprogram is saamgestel na aanleiding van 'n in-diepte literatuuroorsig van bestaande navorsing spesifiek gerig op watter stadium geletterdheidsontwikkeling begin en die bepaling van die proses om te volg vir geletterdheidsontwikkeling. Deur hierdie multimediaprogram word Fonologiese Prosessering, Skrifbewustheid, Mondelinge Taalvaardighede, Vroegtydige Leesgedrag, Letterkennis en Vroeë Woordherkenning, Taalontwikkeling, Luister- en Leesbegrip bevorder. Die gevolgtrekking van die navorsing dui daarop dat daar baie waarde opgesluit is in die voorlees en herhaling van rympies, liedjies en stories. Die voorleesmetode van stories deur middel van die skrifverwysingsstyl-leesmetode wat verwys na die uitwysing van letters tydens die voorlees van ‘n storie, bevorder die aanleer van letters en klanke. Deur die kleuter of leerder te lei om afleidings te maak, word begrip gevorm.

Abstract:

This Masters Thesis describes the continuation of the Snow Probe development. The focus of this project was to establish the rotational shear vane as a useful tool in avalanche safety work as well as develop a robust method for measuring the applied torque. A new and novel way of measuring the torque on a rotational shear vane has been developed to illustrate its effectiveness. The new system measures the power supplied to a cordless drill to get an indication of the applied torque. This was done because it was found that the earlier method of using a strain gauge/cantilever system repeatedly failed to work, largely due to complexity. The snow probe in its present embodiment has been shown to provide a good clear indication of the snow profile under easily repeated circumstances. Shear strength results are at this stage not sufficiently for reliable quantitative results. However the probe in its present form is able to give pictorial impressions of the snow pack that compare well to current hand hardness profiles derived from snow pit methods. Even in its current form the snow probe is able to collect useful snow profile data in a matter of minutes, much quicker than conventional snow pit methods. A loose relationship was found to exist between the approach angle of a shear vane blade and the clarity of the snow profile. These relationships are relatively inaccurate at present due to lack of rotational velocity data and therefore pproach angle data. It is believed that the addition of a rotation counter would greatly increase the accuracy of the probe results and enable a shear strength profile to be quantified. Further developments and testing are underway with a view to forming a company around the snow probe.

Abstract:

The purpose of this dissertation is to investigate the development of the notion of property concept since the promulgation of the Constitution of South Africa 108 of 1996 with special reference to the influence of statutory developments and especially the influence of Prevention of Illegal Eviction from and Unlawful Occupation of Land Act 19 of 1998. In the preamble to the Constitution it is made very clear that the injustices of the past are recognised and that it is endeavoured to rectify the division of the past and that all efforts are to be made to build a future that is characterised for the acknowledgement of human rights, democracy, equality and peaceful co-existence. In the Bill of Rights the right to property is acknowledged as a fundamental right and is it also mentioned that the state must respect, protect, promote and fulfil the rights in the Bill of Rights. Before the Constitution common law protection for ownership was well established, but no statutory protection for ownership existed. The effect of the property clause (section 25) of the Constitution was that not only ownership, but also other rights to property protected. The property clause prescribes that no one may be deprived of his property, except in terms of law of general application, and no law may permit arbitrary deprivation of property. No fundamental right is absolute with the effect that conflict may arise between the different clauses of the Bill of Rights. A typical example may be where the rights of an owner of immovable come into conflict with another person's right to housing. It must, however, always be borne in mind that no fundamental right is absolute that it is possible, under certain circumstances, to limit a fundamental right. This limitation may also occur in the case of property rights. Certain statutory developments took place since the promulgation of the Constitution. The most important of these developments is of course the Prevention of Illegal Eviction from and Unlawful Occupation of Land Act 19 of 1998. In terms of this Act it is required that certain formalities are to be fulfilled before an unlawful occupier may be evicted from property. The relevant part of the Act is the definition of an illegal occupier. Despite the fact that it was decided in several court cases that an illegal occupier does not include a person who previously had permission to occupy the property, it was decided by the Supreme Court of Appeal in Ndlovu v Ngcobo : Bekker v Jika that the act is applicable to such occupiers and specifically to lessees who's lease agreements have expired or a mortgagor who's mortgage has been foreclosed and who now refuses to vacate the property in question. The key findings are that the property concept has developed drastically since the Constitution. In regard to statutory development the most important development was the Prevention of Illegal Eviction from and Unlawful Occupation of Land Act which was found to be applicable to all unlawful occupiers of property, regardless of the fact that the occupiers may previously have occupied the property lawfully. The Legal Amendment Bill is to rectify this in order to ensure that the Prevention of lllegal Eviction from and Unlawful Occupation of Land Act will no longer be applicable to such occupiers and specifically to lessees who's lease agreements have expired or mortgagors who's bond have been called up and who now refuse to vacate the property in question This amendment will bring the (often) conflicting fundamental rights to property and housing into a greater degree of harmony, even though it will not solve all problems. It is the duty of the State to address this and all other potential conflict between different fundamental rights. The method used in this dissertation was the analytical study of statutes, court cases and articles in legal magazines.

Thesis (MSocialWork) -- University of Stellenbosch, 2002.
ENGLISH ABSTRACT: Since 1988 it became practice for welfare organisations to submit an evaluation of their welfare programme as part of their application for state funding for the next year. Included in this evaluation is a section on the cost efficiency of the programme. After the first democratic election in 1994 a number of processes were started to develop new welfare policies for the country. In all of these processes cost efficiency is seen as a principle, but in spite of this, so it seems from the documents, is the evaluation of cost efficiency still a problem. The question therefore arises: What is the present status of the evaluation of the cost efficiency of social services after twelve years of program evaluation? Only a few studies on the methodology of the evaluation of cost efficiency within the South African context were found through the literature study. An exploratory study was therefore undertaken to determine what the reasons could be why so little progress was made with cost effiency evaluation. The empirical study focussed on residential facilities for older persons and was done within one welfare organisation in the Western- and Southern Cape. A sample of twenty managers was randomly selected and fifteen respondents returned the questionaire. It is a potential danger that managers of residential facilities for older persons could see the evaluation of the services rendered as just another administrative task, because of the very strong link between evaluation and the application for state funding. The researcher therefore wanted to ascertain what the attitude of the managers is towards the evaluation of their services, and especially the evaluation of the cost-efficiency thereof. It was found that the managers are positive towards program evaluation and the evaluation of cost efficiency, but the majority of them responded that the lack of guidelines and manuals is a deficiency. The lack of proper measuring instruments was also stressed. The research also shown that the managers conceptualize cost efficiency mainly in terms of costs and not as a relation between the outcomes of the programme and the costs thereof. The managers of residential facilities uses the evaluation document that was send out by the department, because it forms part of the application for state funding. This means that the level of program evaluation is actually determined by the department. It was found that this document focused mainly on the measuring of inputs and outputs and not so much of the evaluation of the outcomes of the programme. Based on the results of the study the researcher proposed guidelines to promote the evaluation of the cost efficiency of social services.
AFRIKAANSE OPSOMMING: Dit is sedert 1988 praktyk dat vrywillige welsynsorganisasies jaarliks 'n evaluering van hulle maatskaplikewelsynsprogram moet indien as deel van die aansoek om staatsubsidie vir die volgende jaar. By hierdie evaluering van die maatskaplikewelsynsprogramme is die evaluering van die kostedoeltreffendheid van die program ingesluit. Na die eerste demokratiese verkiesing in 1994 het verskeie prosesse aan die gang gekom om nuwe maatskaplikewelsynsbeleid vir Suid-Afrika te ontwikkel. In al die dokumente wat deur die prosesse ontwikkel is, word die kostedoeltreffendheid van maatskaplikewelsynsdienste as 'n belangrike beginsel gestel. Tog blyk dit, uit die verslae van sommige van die prosesse, dat die evaluering van kostedoeltreffendheid 'n probleem blyk te wees. Die vraag ontstaan dan tereg: Wat is die huidige stand van die evaluering van die kostedoeltreffendheid van maatskaplikewelsynsprogramme twaalf jaar sedert die implementering van programevaluering? Uit die literatuurstudie het dit geblyk dat daar min studies in Suid-Afrika bestaan wat handel oor die metodiek van kostedoeltreffendheidsevaluering van maatskaplikewelsynsprogramme. Verkennende navorsing is onderneem om vas te stel waarom daar oënskynlik min vordering gemaak is met die evaluering van kostedoeltreffendheid van maatskaplikewelsynsprogramme. Die empiriese studie het gefokus op residensiële fasiliteite vir ouer persone en die navorsing is uitgevoer by een welsynsorganisasie in die Wes- en Suid-Kaap. 'n Steekproef van twintig bestuurders is op ewekansige wyse geselekteer en vyftien respondente het die vraelys teruggestuur. Die gevaar bestaan dat, vanweë die sterk verband tussen die evaluering van die program en die aansoek vir subsidie, die evaluering van die maatskaplikewelsynsprogram bloot net as nog 'n administratiewe taak gesien kan word. Daarom wou die navorser vasstel wat die bestuurders van residensiële versorgingsprogramme vir ouer persone se houding jeens programevaluering en die evaluering van die kostedoeltreffendheid van die program is. In die studie is bevind dat die bestuurders positief jeens programevaluering en die evaluering van die kostedoeltreffendheid van die programme is, maar die oorgrote meerderheid bestuurders het aangedui dat hulle dit as 'n leemte sien dat daar min riglyne of handleidings bestaan. Die gebrek aan meetinstrumente is ook beklemtoon. Uit die studie het dit verder geblyk dat die bestuurders die konsep kostedoeltreffendheid hoofsaaklik in terme van koste verstaan, en nie in terme van 'n verhouding van die uitkomste van die program tot die koste daarvan nie. Die bestuurders van residensiële fasiliteite voltooi jaarliks die evalueringsdokument van die betrokke staatsdepartement, omdat dit deel vorm van die aansoekprosedure vir staatsubsidie. Hierdie dokument bepaal derhalwe die vlak van programevaluering. Dit het uit die studie geblyk dat die dokument wat gebruik word grootliks fokus op die meting van insette en uitsette en nie soseer op die uitkomste van die welsynsprogramme nie. Gebaseer op die bevindinge van die navorsing is riglyne voorgestel wat sal meewerk om die evaluering van die kostedoeltreffendheid van maatskaplike dienste te bevorder.

Thesis (MA) -- University of Stellenbosch, 2004.
ENGLISH ABSTRACT: This study was undertaken with a view to evaluate the effect of music education on the self-concept of the learner with attention deficit hyperactivity disorder. Four learners diagnosed with attention deficit hyperactivity disorder were asked to participate in a music program presented for two terms by the researcher. The selfconcept of the learners was recorded through interviews and questionnaires by the learners and their parents before the study commenced. Observations by the researcher and objective observer were used to monitor the learners' progress during the course of the lessons. After the completion of the music program the learners and their parents were again asked to participate in an interview and to complete a questionnaire. This study revealed that music education is a great enjoyment to these learners and the self-concept and self-confidence of some of the learners improved. A literature review was done in order to obtain a perspective on attention deficit hyperactivity disorder. A historical overview provided insight into the development of this disorder necessary to describe it properly. The study also focuses on various intervention techniques which can be used by parents and teachers. In addition, the study focuses on the role of music education and music practice on the various developmental levels of the learner and how music can indeed affect relaxation and be responsible for lifelong learning. It is recommended that the learners continue with mUSIC education, because it provides them with a sense of success and it plays a vital role in the cognitive development of the learner. This, in tum, leads to lifelong learning: an influence that will remain an irrevocable part of the child for the rest of his/her life.
AFRIKAANSE OPSOMMING: Hierdie studie is onderneem met die doelom die uitwerking van musiekonderrig op die selfbeeld van die leerder met aandagafleibaarheid-hiperaktiwiteit te evalueer. Vier leerders wat gediagnoseer is met aandagafleibaarheid-hiperaktiwiteit is genader om 'n musiekprogram, aangebied deur die navorser, vir twee kwartale by te woon. Die selfbeeld van die leerders, wat vooraf deur middel van onderhoude en vraelyste deur die leerders en hulouers voltooi is, is geëvalueer. Die leerders se vordering is tydens die lesse deur middel van observering en objektiewe waarneming bepaal. Na afloop van die musiekprogram is die leerders en hulouers weer gevra om 'n onderhoud en vraelys te voltooi. Uit die studie blyk dit dat musiekonderrig 'n groot mate van genot vir die leerders is en daar was 'n verbetering in selfbeeld en selfvertroue by sommige van die leerders. 'n Literatuuroorsig bied insig oor die omvang van aandagafleibaarheid-hiperaktiwiteit en 'n historiese oorsig oor die verloop van die proses wat tot 'n beskrywing van die versteuring lei, word bekyk. Die verskeie intervensie-tegnieke wat deur ouers en opvoeders toegepas kan word, word bespreek. Verder word die rol wat musiekonderrig en musiekbeoefening op die verskillende ontwikkelingsvlakke van die leerder speel aangespreek, asook hoe musiek 'n ontspannende effek kan hê en verantwoordelik kan wees vir lewenslange leer. Dit word aanbeveel dat leerders volhou met musiekonderrig, omdat dit 'n gevoel van sukses verskaf en 'n belangrike rol speel in die leerder se kognitiewe ontwikkeling. Laasgenoemde is gevolglik verantwoordelik vir lewenslange leer: 'n onherroeplike invloed op die leerder vir die res van sy/haar lewe.

Abstract:

El vals criollo limeño es uno de los géneros más tradicionales en el Perú. La guitarra es el instrumento por excelencia con el cual se le ejecuta y entre sus mayores representantes se alza la figura de Carlos Hayre. Hayre fue un músico con formación mixta forjada por la cultura popular, los estudios de música académica y una instrucción autodidacta que determinaron una personalidad renovadora y experimental que planteó cambios estructurales en el género. Estos cambios afectaron los fundamentos del estilo de ejecución del género tanto desde el punto de vista de los cultores de la tradición de La Vieja Guardia y de La Generación Pinglo, como desde la de sus coetáneos, quienes también desarrollaron una estética distinta a la tradicional que a la postre sería más difundida y reconocida. Carlos Hayre fue un determinante de cambio en la historia del género gracias a sus propuestas en cuanto a la ejecución de la guitarra con criterios dinámicos y técnicos provenientes de su formación en guitarra clásica. También se dieron cambios determinados por sus criterios de composición orquestal aplicados a la guitarra en cuanto a la forma, con nuevos criterios de libertad estructural, a la armonía, determinados por los fundamentos de la tonalidad extendida, y a la melodía, fundamentados en las mayores posibilidades de movimiento y variedad que le brindaban sus nuevos pilares armónicos. Carlos Hayre es un artista transcendental en la historia del vals criollo limeño, y esta consideración está solventada en el respeto y admiración de una comunidad integrada por actores culturales de distintas disciplinas que lo recuerdan no solo por su gran calidad humana, sino por el valor y la trascendencia de su música.
The Lima Creole waltz (Popular gender linked to the Viennesse waltz and the Creole of Lima) is one of the most traditional genres in Perú. The guitar is the instrument par excellence with which it is played and among its greatest representatives stands the figure of Carlos Hayre. Hayre was a musician with a mixed training forged by popular culture, academic musical instruction and a self-taught training that determined a renewing and experimental personality that posed structural changes in the genre. These changes affected the foundations of the genre's performance style both from the point of view of the cultists of the tradition of The Old Guard (The generation of the beginning of the genre) and The Pinglo Generation, as well as from that of their contemporaries who also developed an aesthetic different from the traditional one and that in the end would be more widespread and recognized. Carlos Hayre was a determinant of change in the history of the genre thanks to his proposals regarding the performance of the guitar with dynamic and technical criteria coming from his training in classical guitar. There were also certain changes due to his orchestral composition criteria applied to the guitar in terms of form, with new criteria of structural freedom, to harmony, determined by the fundamentals of the extended tonality, and to melody, based on the new possibilities of movement and variety that gave him his new harmonic fundamentals. Carlos Hayre is an artist who is transcendental in the history of the Lima Creole waltz, and this consideration is based on the respect and admiration of a community made up of cultural actors from different disciplines who remember him not only for his great human quality but also for the value and significance of his music.

Denne rapporten fokuserer på en eksperimentell undersøkelse av fase inversjon for olje-vann blandinger. Undersøkelsen har blitt utført ved batch forsøk og direkte strømnings forsøk (uten å øke den dispergerte fasen), og både rå-olje og modell-olje har blitt brukt. Når modell-olje har blitt brukt, har også hydrofobe surfaktanter blitt brukt for å prøve å få oljen til å oppføre seg som en rå-olje og forsøke å kontrollere inversjons prosessen. Spesiell fokus har blitt rettet mot formasjon av multiple emulsjoner (w/O/W), og hvordan dette kan føre til fase inversjon. Visuelle bevis er presentert. Den første delen av denne rapporten er teoretisk, og inneholder den nødvendige teorien for å kunne tolke de eksperimentelle resultatene. Den inneholder også en beskrivelse av det eksperimentelle oppsettet som er brukt, og hvilke forsøk som er utført. Den siste delen av rapporten inneholder en seksjon med resultatene fra forsøkene. Denne delen inneholder trykkfall kurver, korde lengde målinger, visuelle bevis, og en samling av oppdagede, eller bekreftede relasjoner fra de utførte batch forsøkene. Resultatene er diskutert og konklusjoner er gjort, basert på det eksperimentelle arbeidet og eksisterende teorier. Resultatene er drøftet og det er konkludert med at fase inversjon kan skje i direkte strømnings forsøk med råolje (fra Grane feltet) som et resultat av at det dannes multiple emulsjoner over tid. Ved å bruke en korrekt mengde surfactant kan dette også skje når man bruker modell olje (Primol 352).Det blir også konkludert med at Cryo ESEM tekonologi kan bli brukt til å dokumentere formasjonen av multiple emulsjoner med større sikkerhet enn ved metoder brukt i tidligere arbeid forfatterne kjenner til.

Thesis (MPhil (Modern Foreign Languages. Hypermedia for Language Learning))--University of Stellenbosch, 2010.
ENGLISH ABSTRACT: The ancient Roman poet Vergil’s great literary epic, the Aeneid, is written in Latin. This so-called “dead” language is already almost three thousand years old and had a rich history and extensive influence on the Western world. The most influential development of the modern era is the World Wide Web (WWW). Hypertext drives the Web. The translation of just one book of the Aeneid can be a protracted process for the Latin student. Usually a great deal of information must be consulted to translate just one line into idiomatic Afrikaans or English. Hypertext can manage, link and rapidly make available large amounts of information. A discussion of Aeneidos Electronicum (“The Electronic Aeneid”) – a web-based electronic text commentary of Book I of the epic – shows the effectiveness of hypertext as a medium to facilitate the translation of the Aeneid. Moreover an examination of the Web determines the extent and nature of Vergil’s presence on it. Finally a critical evaluation of five websites provides an overview of the available resources for the reader/researcher of the classical poet and his works on the Web. The Aeneidos Electronicum-project attempts to show how hypertext can be utilised to make the translation of the Aeneid expeditious and translation aid more accessible. The aim of the project is to support and expand Vergil’s place in the field of computer assisted language learning. The examination and evaluation of the classical poet’s presence on the Web wishes to confirm that his and his works’ enduring influence and impact not only exists on paper, but also in cyberspace. Chapter 2 deals with Latin and Vergil respectively. Chapter 3 discusses the theory of good hypertext and web design. Chapter 4 describes and explains the contents, structure, navigation and design of the Aeneidos Electronicum-project. Chapter 5 examines Vergil’s presence on the Web and critically evaluates five websites according to the principles of good web design. Aeneidos Electronicum utilises hypertext’s ability to manage and link large amounts of information to produce an electronic text commentary of Book I of Vergil’s Aeneid. It is web-based and follows the guidelines of good hypertext and web design to be a userfriendly and extremely functional electronic translation aid. Similar websites exist, but its object is to make Latin students’ experience of Vergil and his great epic easy, informative and enriching. Vergil’s presence on the Web is considerable and there is a wide variety of websites with information and interactivity for study of the classical poet and his works available to the student/teacher/researcher as well as the lay person. The random sample of five websites shows not only the application of good and less effective web design principles, but also the predominantly good quality and importance of the presentations. Thus Vergil and his works gain further ground in computer assisted language learning and he lives on in the 21st century with all the possibilities that the Web and hypertext can offer.
AFRIKAANSE OPSOMMING: Die antieke Romeinse digter Vergilius se grootse literêre epos, die Aeneïs, is in Latyn geskryf. Dié sogenaamde “dooie” taal is al ongeveer drieduisend jaar oud en het ’n ryke geskiedenis en omvattende invloed op die Westerse wêreld gehad. Die invloedrykste tegnologiese ontwikkeling van die moderne era is die Wêreldwye Web (WWW). Hiperteks dryf die Web. Die vertaling van net een boek van die Aeneïs kan ’n langdurige proses vir die Latyn-student wees. ’n Magdom inligting moet gewoonlik geraadpleeg word om net een reël in idiomatiese Afrikaans of Engels te vertaal. Hiperteks kan groot hoeveelhede inligting hanteer, verbind en vinnig beskikbaar stel. ’n Bespreking van Aeneidos Electronicum (“Die Elektroniese Aeneïs”) – ’n webgebaseerde elektroniese tekskommentaar van Boek I van die epos – toon die effektiwiteit van hiperteks as ’n medium om die vertaling van die Aeneïs te vergemaklik. Voorts bepaal ’n ondersoek van die Web die omvang en aard van Vergilius se teenwoordigheid daarop. Ten slotte bied ’n kritiese evaluering van vyf webwerwe ’n oorsig van die beskikbare hulpbronne vir die leser/navorser van die klassieke digter en sy werke op die Web. Die Aeneidos Electronicum-projek poog om te toon hoe hiperteks ingespan kan word om die vertaling van die Aeneïs te bespoedig en vertaalhulp meer toeganklik te maak. Die oogmerk van die projek is om Vergilius se plek in die rekenaarondersteunde taalonderrigveld te ondersteun en uit te brei. Die ondersoek en evaluasie van die klassieke digter se teenwoordigheid op die Web wil bevestig dat hy en sy werke se blywende invloed en trefkrag nie net op papier voortleef nie, maar ook in die kuberruim. Hoofstuk 2 behandel onderskeidelik Latyn en Vergilius. Hoofstuk 3 bespreek die teorie van goeie hiperteks en webontwerp. Hoofstuk 4 beskryf en verklaar die inhoud, struktuur, navigasie en ontwerp van die Aeneidos Electronicumprojek. Hoofstuk 5 ondersoek Vergilius se teenwoordigheid op die Web en evalueer krities vyf webwerwe volgens die beginsels van goeie webontwerp. Aeneidos Electronicum benut hiperteks se vermoë om groot hoeveelhede inligting te hanteer en te skakel om ’n elektroniese tekskommentaar van Boek I van Vergilius se Aeneïs teweeg te bring. Dit is webgebaseerd en volg die riglyne van goeie hiperteks en webontwerp om ’n gebruikersvriendelike en uiters funksionele elektroniese vertalingshulpmiddel te wees. Soortgelyke webwerwe bestaan, maar dit het ten doel om Latyn-studente se ervaring van Vergilius en sy grootse epos gemaklik, insiggewend en verrykend te maak. Vergilius se teenwoordigheid op die Web is aansienlik en daar is ’n wye verskeidenheid webwerwe met inligting en interaktiwiteit vir studie van die klassieke digter en sy werke vir die student/onderwyser/navorser asook die leek beskikbaar. Die steekproef van vyf webwerwe toon nie net die toepassing van goeie en minder doeltreffende webontwerpbeginsels nie, maar ook die oorwegend goeie gehalte en belangrikheid van die aanbiedinge. Dus wen Vergilius en sy werke nog verder veld in rekenaarondersteunde taalonderrig en leef hy in die 21ste eeu voort met al die moontlikhede wat die Web en hiperteks kan bied.

Abstract:

Problems with students’ performance in Mathematics at tertiary level are common in South Africa − as it is worldwide. Pass rates at the university of technology where the researcher is a lecturer, are only about 50%. At many universities it has become common practice to refer students who do not have a reasonable chance to succeed at university level, for additional support to try to rectify this situation. However, the question is which students need such support? Because the Grade 12 marks are often not perceived as dependable, it has become common practice at universities to re-test students by way of an entrance exam or the "National Benchmark Test"- project. The question arises whether such re-testing is necessary, since it costs time and money and practical issues make it difficult to complete timeously. Many factors have an influence on performance in Mathematics. School-level factors include articulation of the curriculum at different levels, insufficiently qualified teachers, not enough teaching time and language problems. However, these factors also affect performance in most other subjects, but it is Mathematics and other subjects based on Mathematics that are generally more problematic. Therefore this study focused on the unique properties of the subject Mathematics. The determining role of prior knowledge, the step-by-step development of mathematical thinking, and conative factors such as motivation and perseverance were explored. Based on the belief that these factors would already have been reflected sufficiently in the Grade 12 marks, the correlation between the marks for Mathematics in Grade 12 and the Mathematics marks at tertiary level was investigated to assess whether it was strong enough for the marks in Grade 12 Mathematics to be used as a reliable predictor of success or failure at university level. It was found that the correlation between the marks for Mathematics Grade 12 and Mathematics I especially, was strong (r = 0,61). The Mathematics marks for Grade 12 and those for Mathematics II produced a correlation coefficient of rs = 0,52. It also became apparent that failure in particular could be predicted fairly accurately on the basis of the Grade 12 marks for Mathematics. No student with a Grade 12 Mathematics mark below 60% succeeded in completing Mathematics I and II in the prescribed two semesters, and only about 11% successfully completed it after one repetition. The conclusion was that the reliability of the prediction based on the marks for Grade 12 Mathematics was sufficient to refer students with a mark of less than 60% to receive some form of additional support.

ENGLISH ABSTRACT: Through the establishment of victim support centres, NICRO Eastern Cape aims to develop community networks that render available and appropriate support services to victims of crime. Social workers empower volunteers to run the centres. In order for the social workers to empower volunteers, they need to clearly understand their role in the empowerment process. The goal of the study is to clarify the role of social workers when empowering volunteers at community victim support centres. The profile, motivation and current empowerment of volunteers at NICRO Eastern Cape were determined and described by means of questionnaires. The respondents were fifteen volunteers and three social workers. Conclusions and recommendations were made which focused, among other aspects, on the training of social workers and strategic planning around empowerment. The framework of this research report can be utilized by social workers in the empowering of volunteers, which could possibly lead to victim support centres that are managed by volunteers, as representatives of communities, independently from NICRO.
AFRIKAANSE OPSOMMING: By die slagofferondersteuningsentrums te NICRO Oos-Kaap word daar gepoog om 'n gemeenskapsnetwerk te ontwikkel waardeur slagoffers van misdaad beskikbare en toepaslike ondersteuning ontvang. Dit word gedoen deur die bemagtiging van vrywilligers deur maatskaplike werkers. Ten einde die vrywilligers te bemagtig, is dit belangrik dat maatskaplike werkers hul rol in die proses van bemagtiging begryp. Die doel van die studie is om die rol van die maatskaplike werker uit te klaar met die bemagtiging van vrywilligers by 'n gemeenskapslagofferondersteuningsentrum. Die profiel, motivering en huidige bemagtiging van vrywilligers by NICRO Oos-Kaap is deur middel van vraelyste bepaal en ontleed. Die respondente het uit vyftien vrywilligers en drie maatskaplike werkers bestaan. Gevolgtrekkings is gemaak en aanbevelings gedoen wat onder andere fokus op die opleiding aan maatskaplike werkers en strategiese beplanning rondom bemagtiging. Die raamwerk van hierdie navorsingsverslag sal deur maatskaplike werkers benut kan word in die bemagtiging van vrywilligers en dit kan moontlik aanleiding gee tot slagofferondersteuningsentrums wat onafhanklik van NICRO deur vrywilligers, as verteenwoordigers van gemeenskappe, bestuur word.

The study investigated the effect of using projective narratives and drawings that depict diminished fear, on the anxiety levels of a group of children living in children’s homes, by means of a mixed methodology. The sample consisted of 30 middle childhood children (mean age = 9.60 years, SD = 1.13) from three children’s homes in the Western Cape. Drawings were used to elicit content of fear or anxiety (anxiety evoking drawing/bangmaaktekening) and proposed coping (anxiety lessening drawing/bangwegvattekening). After completing the anxiety provoking drawing, participants in the experimental group were asked to tell a story to other children with a similar fear to lessen/take that fear away (projective narrative). The Spence Childhood Anxiety Scale (SCAS) was completed after each drawing, and drawings evaluated through the use of anxiety scales, to measure changes in anxiety levels according to the concept of triangulation. The categories ghosts, snakes, and people were found to be the most prevalent content of fear from anxiety provoking drawings, and undifferentiated fears were also common within this population. Control of anxiety from anxiety lessening drawings indicated a definite prevalence of emotion focused (secondary) coping strategies, specifically religious solace. The content of projective narratives echoed this finding, although proposed solutions were more differentiated. Ownership of projections also occurred. The experimental effect was not significant, although mean anxiety levels were considerably lower in the drawings in comparison with that of the SCAS. Drawings are thus seen as an effective, nonthreatening technique to study anxiety phenomena. A comparison of the mean item scores of the SCAS subscales indicated that symptoms of separation anxiety, generalised anxiety disorder, and obsessivecompulsive anxiety disorder were prevalent among this group of children in children’s homes. A clear distinction was found between markers of state- and trait-anxiety through the qualitative analysis of the drawings, with anxiety lessening drawings showing definite diminished state-anxiety, although more established markers of trait-anxiety did not necessarily change. There are also indications that transference of activated negative emotional stimuli occurred on an unconscious level between the two drawings. Introducing the combination of projective narratives in the intervention stage of the study appeared to facilitate learning or the experience of observed positive affect in anxiety lessened drawings. Future research would benefit from including a normative group to establish more clear markers of state- and trait-anxiety in drawings, and by the use of a bigger sample to investigate factor loadings of the SCAS among children in children’s homes. The high prevalence of anxiety symptoms in this population emphasises their status as a vulnerable population, and the need for possible group intervention – specifically the psycho-education of effective coping strategies for anxiety.

Abstract:

The goal of a gas turbine engine designer is to reduce the amount of coolant used to cool the critical turbine surfaces, while at the same time extracting more benefit from the coolant flow that is used. Fan-shaped holes offer this opportunity, reducing the normal jet momentum and spreading the coolant in the lateral direction providing better surface coverage. The main drawback of fan-shaped cooling holes is the added manufacturing cost from the need for electrical discharge machining instead of the laser drilling used for cylindrical holes. This research focused on examining the performance of fan-shaped holes on two critical turbine surfaces; the vane and endwall. This research was the first to offer a complete characterization of film-cooling on a turbine vane surface, both in single and multiple row configurations. Infrared thermography was used to measure adiabatic wall temperatures, and a unique rigorous image transformation routine was developed to unwrap the surface images. Film-cooling computations were also done comparing the performance of two popular turbulence models, the RNG-kÎµ and the v2-f model, in predicting film-cooling effectiveness. Results showed that the RNG-kÎµ offered the closest prediction in terms of averaged effectiveness along the vane surface. The v2-f model more accurately predicted the separated flow at the leading edge and on the suction side, but did not predict the lateral jet spreading well, which led to an over-prediction in film-cooling effectiveness. The intent for the endwall surface was to directly compare the cooling and aerodynamic performance of cylindrical holes to fan-shaped holes. This was the first direct comparison of the two geometries on the endwall. The effect of upstream injection and elevated inlet freestream turbulence was also investigated for both hole geometries. Results indicated that fan-shaped film-cooling holes provided an increase in film-cooling effectiveness of 75% on average above cylindrical film-cooling holes, while at the same time producing less total pressure losses through the passage. The effect of upstream injection was to saturate the near wall flow with coolant, increasing effectiveness levels in the downstream passage, while high freestream turbulence generally lowered effectiveness levels on the endwall.

ENGLISH ABSTRACT: The purpose of this study is to investigate the role of sport psychology injunior tennis and to determine: • whether coaches make use of psychological interventions, • whether coaches consider psychological interventions in junior tennis to be important, • what kind of psychological interventions coaches make use of, and • what kind of problems coaches encounter while teaching psychological interventions to junior tennis players. Questionnaires were mailed off to all professional tennis coaches who are registered with Tennis South Africa. The questionnaire which the coaches voluntarily answered, was an abbreviated, revised version of the questionnaire used by Gould et al. (1999a) for their study. \ The results of this study show that coaches: • regard the teaching of psychological interventions to junior tennis players as very important. • perceived the following as the most important psychological dimensions for junior tennis players: motivation, concentration, enjoyment, self-confidence and goal setting. • find the teaching process of psychological interventions to junior tennis players difficult. • encounter practical problems in the teaching of psychological interventions to junior tennis players. Lack of time is mentioned most often. Based on these outcomes, it is concluded that sport psychology has an important role to play in junior tennis. More research is needed to develop techniques and methods to effectively teach psychological interventions to junior tennis players.
AFRIKAANSE OPSOMMING: Die doel van die studie is om die rol van sportsielkunde in junior tennis te ondersoek deur die volgende te bepaal: • of afrigters van sielkundige intervensies gebruik maak, • of afrigters dink dat sielkundige intervensies belangrik is in junior tennis, • van watter sielkundige intervensies afrigters gebruik maak, en • watter probleme afrigters ondervind gedurende die onderrig van sielkundige intervensies aan junior tennisspelers. Vraelyste is gestuur aan aIle professionele tennisafrigters wat by Tennis Suid-Afrika geregistreer is. Die vraelys wat die afrigters vrywillig beantwoord het, was 'n verkorte, hersiene weergawe van die vraelys wat deur Gould et al. (1999a) in hulle studie gebruik is. Die resultate van die studie toon dat afrigters: • die onderrig van sielkundige intervensies aan junior tennisspelers as belangrik beskou. • die volgende sielkundige dimensies in junior tennis as die belangrikste beskou: motivering, konsentrasie, genot, selfvertroue en doelwitstelling. • die onderrigproses verbonde aan sielkundige intervensies moeilik vind. • praktiese probleme ondervind met die onderrig van sielkundige intervensies aan junior tennisspelers. 'n Gebrek aan tyd is uitgesonder as die probleem wat die meeste voorkom. Gebaseer op die resuitate, is daar tot die gevolgtrekking gekom dat sportsieikunde 'n belangrike rol te speel het in junior tennis. Verdere navorsing word benodig am tegnieke en metodes daar te stel om die sieikundige intervensies effektief aan junior tennisspelers te onderrig .

Abstract:

Vanntrevekst er den viktigste årsaken til aldring i polymerisk isolasjon i mellomspenningskabler. Sia vanntrær ikke dannes ved lav relativ fuktighet (R.H.), er det viktig å holde relativ fuktighet i isolasjonen lav så lenge som mulig. Dette kan gjøres ved å beskytte isolasjonen med ei kappe av to polymerer. For å beregne vanntransporten inn i isolasjonen, må kappematerialenes vanntransportegenskaper kjennes. For noen polymerer varierer vanntransportegenskapene med det hydrostatiske trykket og den relative fuktigheta (damptrykket). I denne oppgaven er det målt transportkoeffisienter for to kandidater til kappematerialer: én halvledende lineær lavdensitetspolyetylen (LLDPE) og én halvledende eterbasert termoplastisk polyuretan (TPU). Noen av prøvene har vært utsatt for strekking til 10 % statisk forlengelse og etterfølgende relaksasjon i forkant av forsøkene, for å finne ut om ei slik mekanisk påkjenning har noe å si for transportkoeffisientene. Det er gjort målinger av metningskonsentrasjoner ved 0,1 MPa og 30 MPa hydrostatisk trykk, og permeabilitetsmålinger ved forskjellige damptrykk. Konklusjonene om metningskonsentrasjonen i TPU ved 0,1 MPa og 30 MPa hydrostatisk trykk trekkes delvis på grunnlag av et tidligere arbeid. I tillegg har diffusjons- og løselighetskoeffisientene for ustrukket TPU blitt målt ved forskjellige damptrykk. Det er ikke funnet noen signifikant sammenheng mellom det hydrostatiske trykket og vannopptaket i noen av materialene, hverken med strukkede eller ustrukkede prøver. Det er heller ikke funnet at strekking har noen signifikant innvirkning på transportkoeffisientene, bortsett fra at strukket TPU viser en ca. 15 % større metningskonsentrasjon enn ustrukket TPU. Det er funnet at transportkoeffisientene i TPU varierer med damptrykket, men hverken diffusjons-, løselighets- eller permeabilitetskoeffisienten varierer mer enn med en faktor 3 mellom 20 % R.H. og 80 % R.H. For LLDPE er det ikke gjort like omfattende undersøkelser, men permeabilitetskoeffisienten i det materialet viser ingen damptrykkavhengighet.
